Answer:
(a) 1, 2
(b) 4
Step-by-step explanation:
(a) 9x +81 = 9·x +9·9 = 9(x +9) . . . . . . matches first and second choices
__
(b) 10 +14y -5 -y = (14y -y) +(10 -5) = 13y +5 . . . . . . matches fourth choice only
Period is 1
<em><u>Solution:</u></em>
Given that,
<em><u>For the simple harmonic motion equation:</u></em>
To find: Period
Use the following form to find the period
Where,
a is the amplitude
c is phase shift
d is vertical shift
<em><u>The period is given as:</u></em>
On comparing,
Thus on comparing we get,
Thus,
Thus period is 1
6×6=6×15+15=6×3+6×3=18+18=36

Answer:
3. θ = 72°
4. C = 108
Step-by-step explanation:
3. Solve for θ.
θ = 360°(s/C) = 360°(24/120) = 72°
__
4. Solve for C.
C = 360°(s/θ) = 360°(12/40°) = 108
I think your answer would be $144
3:2
360 - 144 = 216
216:144
216/72 = 3
144/72 = 2
Hope This Helps!:)
